Physical weathering is: frost, crystallization, exfoliation,, biological and pressure release.
Chemcal weathering: anything with chemicals in it like carbonation, hydrolysis, solution, oxidation and hydration.

The differences are that mechanical weathering breaks rocks into little pieces.. Chemical weathering not only breaks the rock but dissolves it.
1) Chemical and biological sedimentary rocks are produced by chemical weathering instead of the siliciclastic sediments which are created by physical weathering. Because physical weathering is much more often than the chemical weathering there are 10 times more clastic sediments in the earth's crust than chemical and biological sediments.
All physical and chemical properties are different.
SPELLING.
physical weathering is weathering that you can reverse and chemical weathering is where you can' reverse it.
physical: water, wind, and temperature chemical: acid rain and rust
1. Acid rains produce a chemical weathering.2. Chemical weathering involve chemical reactions.
Physical weathering is breaking down of rocks by weather that does not change their chemical components. Chemical weathering is weathering that breaks rocks down by a chemical change.

Chemical weathering is which makes new substances, whereas physical weathering is where rock is changed into smaller pieces of the same substance.
chemical weathering change will most likely make a new substance
A chemical change results in a change in chemical composition, while a physical change does not.

physical change are reversable
